Chlorellidium Vischer, 1936
Holotype species: Chlorellidium tetrabotrys Vischer & Pascher
Publication details: Vischer, 1936: 307
Original publication and holotype designation: Vischer, W. (1936). Studien an heterokonten. Verh. Schweiz. Naturf. Ges. 117: 307 only.
Description: Cells rarely solitary, usually in closely arranged tetrads or groups of 2's or 3's, which often form large, irregular, cushion-like aggregates, sessile on substrates. Cell groups held together by thin or thick, sometimes gelatinized or ruptured cell walls of the mother cell. Adjoining cell groups tightly coherent resisting detachment. Individual cells irregularly spherical or variable in shape due to mutual compression of adjacent cells, 8-18 (-28) _m in diam. Adult cells may contain several nuclei per cell. Chloroplasts (1-) 5-12 per cell. Reproduction by autospores or zoospores. Empty cell walls often remain. resting stages and sexual reproduction unknown. Chlorellidium is rare, on submerged vegetation in freshwater and on soil in coastal and inland regions (Schwarz, 1979). Reproduction by autospores or zoospores. Empty cell walls often remain. Resting stages and sexual reproduction unknown.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,
organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA)
and intended to be published in CD format.
These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above.
The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.
Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
